TO ESTABLISH A BIOLOGICAL STATION IN THE UPPER 
MISSISSIPPI RIVER VALLEY IN THE STATE OF IOWA. 



February 22, 1908. — Committed to the Committee of the Whole House on the state 
of the Union and ordered to be printed. 



Mr. Wilson, of Illinois, from the Committee on the Merchant Marine 
and Fisheries, submitted the following" 

REPORT. 

[To accompany H. R. 13659.] 

The Committee on the Merchant Marine and Fisheries, to whom 
was referred the bill (H. R. 13659) to establish a biological and fish- 
cultural station in the Second Congressional district of the State of 
Iowa, having considered the same, respectfully report with the recom- 
mendation that it do pass with the following amendments, to wit: 

Amend the, title of the bill so as to read: "A l)ill to establish a 
biological station in the Upper Mississippi River Vallej' in the State 
of Iowa." 

Strike out all after the enacting- clause and in lieu thereof insert the 
following: 

That the Secretary of Commerce and Labor is hereby authorized and directed to 
establish and equip a biological station for the propagation of fresh-water mussels 
in the Upper Mississippi River Valley in the State of Iowa, at some suitable point in 
said State to be selected by the Secretary of Commerce and Labor: the cost of estab- 
lishing the same, including purchase of site, construction of buildings and ponds, 
and equipinent, not to exceed the sum of twenty-five thousand dollars: ' 

The purpose of this bill is to make possible the perpetuation of the 
supply of'raw material for the growing American industr}' of manu- 
facturing pearl buttons from the shells of fresh-water mussels and the 
industries collateral to it. B}^ reason of the g-rowth and development 
of this industry the supply of mussel shells is threatened with exhaus- 
tion. By establishing the station proposed in this bill it is believed 
that the question of artificial propagation will be completely solved, 
and that the supply of these shells will be perpetuated by propagation 
which can henceforth be carried on without material additional expense 
to the Government. 

In the last session of Congress an additional appropriation of money 
for scientific investisation under the United States Fish Commission 



2 BIOLOGICAL STATION, UPPER MISSISSIPPI KIVEK VALLEY, IOWA. 



was granted for the purpose of making an investigation of the fresh- 
water mussels of the United States in their relation to the pearl-button 
industry. This investigation was ordered by the Secretary of Com- 
merce and Labor on a showing made to him that this American indus- 
try of manufacturing pearl buttons from the shells of fresh-water 
mussels had grown to considerable proportions during the past few 
3^ears, and that the rapidity with which these shells were being taken 
from the streams of the United States threatened the extinction of these 
mussels, thereby cutting off the source of the raw material for this 
industry and the consequent doom of the industr3\ It was found that 
comparatively little knowledge had been obtained by scientists and 
investigators^ regarding the life histor}^ of our fresh-water mussels, 
and so a commission was created under the supervision of Prof. Paul 
Bartsch, an eminent biological authoi'ity. This commission made an 
examination of many of the principal streams of the country where the 
fresh-water mussels abound, and secured nuich valuable information on 
the subject. The work of this commission has been carried forward 
by Professors Lefevre and Curtis, of the University of Missouri, who, 
by the way, have been conducting these investigations without com- 
pensation. They have determined the mode of development of fresh- 
water mussels, and it has been found to differ from what occurs in 
any of their marine relatives. This difference lies in the fact that the 
embryo lives for a time as a parasite upon fresh-water lishes and can 
only develop in this parasitic condition. 

VVith this fact established, careful experiments have been made in 
inoculating ffshes with these embryo clams. These experiments have 
been conducted by Professors Lefevre and Curtis, and the results 
thereof indicate that the infection of ffshes on a large scale is entirely 
possible, and that there is ample reason to believe in the success of 
such work in building up the suppl}^ of mussels. 

It is clearly pointed out that the steady decline of the beds demands 
some such remedial measures if the supply is to be maintained for 
more than a ver}^ few years. There are still many fundamental scien- 
tific facts relating to the subject which are yet to be determined. For 
example, we do not know the exact breeding seasons of any one of the 
button mussels. We do not know what fish are best adapted to carry- 
ing the glochidia of each species, nor what are the best methods for 
work on a large scale. These facts can be ascertained if proper facili- 
ties for work are provided, and they must be ascertained before the 
process of artificial propagation can be established on a sound basis; 
but since many of them can only be learned by the actual experience 
of attempting artificial propagation on a large scale the investigation 
and the propagation must go hand in hand. To carry on such work 
properly, there is necessary a station, properly equipped, for the whole- 
sale collecting and transporting of fish and mussels to the tanks and 
ponds of the station, where the infections are to be performed. In this 
way there could be liberated hundreds of thousands of fishes loaded with 
these embryo clams, and thus sow these clams broadcast in our rivers. 
It may be added that this process of propagation is in no way harmful 
to the fish. 

The establishment of such a station as is provided for in this bill is 
recommended by the United States (Commissioner of Fisheries. 

The following statement of the principal facts in the life history of 
our fresh-water mussels and the means proposed for increasing the 



D. or a 



.S BIOLOGICAL STATION, UPPER MISSISSIPPI RIVER VALLEY, IOWA. 3 

supply was written by Professors Lefevre and Curtis, who have been 
c: ' and are now conducting experiments under the direction of the United 
^-^^ States Fish Commission. This statement is made a part of the report 
€^ and will be found most interesting. 

The fresh-water clams or mnssels of the United States and similar forms from 
other parts of the world exhibit a mode of development which differs from what 
occurs in any of their marine relatives. This difference lies in the fact that the 
embryo lives for a time as a parasite upon the gills or fins of fresh-water fishes and 
can only develop in this parasitic condition, the life history being, briefly, as tolloxvs: 
The ego-sof the female clam are fertilized by the sperm of the male, which enters the 
body of the female in the water current that brings the clam its food. These eggs begin 
development within the female, where they are contained in sacks formed by the 
animal's gill. Development proceeds as far as a stage known as the glochidium 
(PI ia) which has the two halves of a miniature shell and looks much like a gapmg 
clam shell, l)ut which has none of the internal organs necessary for the life which 
the adult clam leads in the mud of the bottom. . ■,^ ^ ^.u 

The glochidia are shed out of the parent as they become ripe and they tall to the 
bottom where, having no power of locomotion, they remain motionless unless washed 
about by the currents. Experiments prove that they will die before many days 
when left in this condition. If, however, the glochidium chances to come in contact 
with the fins or gills of a fish, which brushes against the silt of the bottom, it fastens 
itself, and within twenty-four hours has caused the skin of the fish to grow over it, 
so that the young mussel is completelv imbedded within the living tissue of the fish. 
In this condition it rests securely, receiving its food from the blood of its host, and 
leadincr a truly parasitic existence, for some months. During this period the glo- 
chidium changes until all the organs of the adult are developed, though it has not 
increased in size. At the end of its parasitic existence, when the organs are fully 
formed the young clam effects the tissue of the fish in such a way that the skin opens 
and the young clam drops to the bottom, where it begins the life which it will lead 
throughout the remainder of its existence. , i ^ i 

The attachment to a fish is entirelv a matter of chance, but where mussels and fish 
are abundant it must often occur under natural conditions, as is seen from the exami- 
nation of fish taken in nature. Still the fishes thus infected will almost never be 
found carrving as many of the parasites as they can without serious injury. 11 the 
fish are taken and placed in a tub or bucket of water containing large numbers ot 
glochidia which have been obtained from removing them from the ripe mussel, it is 
possible to cause the attachment of hundreds of the parasites for every one that 
would be found there by the chance of nature. A fish under 6 inches m lengtii may 
thus be made to carry several hundred glochidia, and thus a thousand fish artificially 
infected may do the work of several hundred thousand in a state of nature. 

Exr.eriments with small numbers of fish under observation in the laboratory 
indicate that their infection on a large scale is entirely possible, and the experiment 
now in progress at La Crosse, in which over 25,000 young fish have thus been infected, 
gives every^indication that such work may be begun even with the scanty knowledge 
we now possess. i i i • 

While there is ample reason to believe in the eventual success ot sucli worR in 
keeping up the supply of mussels, and while the steady decline of the beds demands 
some such remedial measures, if the supply is to be maintained for more than a very 
few years, we are not yet in a position to proceed safely with this work, because we are 
still "io'iiorant of many fundamental scientific facts. For example, we do not know the 
exact^breeding seasons of any one of the button mussels. We do not know w-hat 
fish are best adapted to carrying the glochidia of each species, nor what are the best 
methods for work on a large scale. These facts can be ascertained if proper facilities 
for work are provided, and they must be ascertained before the process ot artificial 
propagation can be established on a sound basis. But since many of them can only 
be learned by the actual experience of attempting artificial propagation on a large 
scale, the investigation and propagation must go hand in hand. To carry on such 
work properly, there is necessary a station properly equipped with boats and a 
steamer for the wholesale collecting and transporting of fish and mussels alive to 
the tanks and ponds of the station where the infection could be performed. 

Nature is prodigal with the supply of glochidia, but so great is the chance against any 
ever fastening themselves upon the fish and against any ever dropping from the fish 
to a place on the bottom where they can succeed in the struggle for lite that, with 
the added destruction of hundreds of millions of shells each year tor commercial 
purposes we may easily exterminate before many years the forms upon which the 
button industry depends. If we can discover the places in the life history where the

waste is greatest and aid the species at those critical stages, there is every reason to 
hope that the supply of mussels can be made to equal if not surpass the numbers 
existing when the first button was cut. 

Legislation against fishing must also be made use of as soon as we know enough of 
the habits and breeding seasons to propose measures that are likely to be a real pro- 
tection. Until then all such laws should be discouraged, however strong maybe the 
wishes of the manufacturers or others to preserve any local supply. We are as likely 
to do harm as good in the making of such laws without adequate knowledge, and the 
revision of bad laws would probably be more difficult than the passage of new ones. 

In conclusion, we may say that the parasitism on the fish makes the propagation 
of mussels go han<l in hand with the propagation of our fresh-water fishes, since the 
fish is in no wise injured by the presence of the parasites. When we liberate a hun- 
dred fish each loaded with its hundreds of glochidia we not only sow the clams 
broadcast on the bottom, but we are also distributing fish which, when their work 
for the clams is done, are just as useful as though they had never known such an 
experience. Wholesale infection gives every promise of success, but the means 
must be provided at once for work on a large scale, and unless something radical is 
soon accomplished the making of buttons from our fresh-water shells is doomed. 

As indicating the size of the pearl button industry in the United 
States and the large number of wage- earners engaged in such manu- 
facture, the following table, taken from the report of the Census of 
Manufacturers for 1905, gives a comparative summary of the industry

These tables do not indicate the full size of this comparatively new 
and growing industry. There are collateral industries which have 
grown up as a result of the manufacture of pearl buttons in the 
United States from fresh water mussels. The sale of pearls and 
baroques which are found in these fresh water mussels has grown to 
large proportions, and a conservative estimate would place the value 
of these pearls at $1,000,000 per annum. Another industry which 
has grown up as a result of the manufacture of buttons from these 
shells is the manufacture of buckles and other articles of adornment, 
including stick pins, brooches, and other articles of jewelry. No data 
is at hand as to the magnitude of this particular industry, but it has 
already attained considerable proportions. 



6 BIOLOGICAL STATION, UPPEE MISSISSIPPI RIVER VALLEY, IOWA. 

In addition the manufacture of button-making' machinery has 
grown to considerable proportions, and the progress in the manu- 
facture of buttons is marked by a corresponding progress in the 
manufacture of labor-saving machines, some of which rival the modern 
type-setting machines in their intricacy and perfection of action. 

In the light of these facts the committee recommends the passage 
of the bill.

60th Congress, } HOUSE OF REPRESENTATIVES, j Kept. 1176, 

M Session. \ . ( Part 2. 



TO ESTABLISH A BIOLOGICAL AND FISH-CULTURAL 
STATION IN THE UPPER MISSISSIPPI RIVER VALLEY. 



March 13, 1908.— Committed to the Committee of the Whole House on the state of 
the Union and ordered to be printed. 



Mr. Spight, from the Committee on the Merchant Marine and Fish- 
eries, submitted the following as the 

VIEWS OF THE MINORITY. 

[To acfompany H. R. 13659.] 

The bill as reported b}' the committee ought not to pass. 

This bill is in the interest of the manufacturers of pearl buttons, 
already, under general law, ampl}^ protected b}' a taritf dut}'. 

This proposition goes far beyond the doctrine of protection. It 
seeks to have the Government appropriate money from the Treasury 
to advance the interests of a private enterprise operated for profit. It 
is altogether different from the tish hatcheries established by the Gov- 
ernment for the breeding of young tishes of approved varieties and 
their distribution to the water courses, lakes, and ponds all over the 
country for increasing the food supply of all the people. The mussel 
is not edible, and its only value is its shell, which is of use solely to 
the button factories. The effect of this bill, if passed, will be to fur- 
nish raw material to these factories. As evidence that such is the 
purpose, an effort was made to amend the bill so as to limit its opera- 
tion to a scientific investigation as to the best method for the propa- 
gation of the fresh -water nuissel. This was promptly voted down b\^ 
the friends of the measure. 

If we inaugurate the policy of appropriating public money for pri- 
vate enterprises, where shall the line be drawn ? It is said that the 
manuf actiu-e of pearl buttons, ornaments, etc. , is a yoimg and grow- 
ing industry in the United States, and that it gives emplo} nient to 
many wage-earners. Grant that this is so. It is equally true that it 
is a profitable business to those engaged in it or the}" would seek other 
avenues of investment. They are not in the business from any motiv^es 
of patriotism or for the public good, but solely for private gain. The 
laborers are given work to do not because of S3^mpathy for the unem- 
ployed, but because their services are profitable to their employers. 



2 BIOLOGICAL AND FISB-CULTURAL STATION. 

Then why should the public Treasury be made to. contribute to their 
already profitable business ? , j , • 

While the bill as originally presented has been so amended by its 
friends as to read, "A biological and fish-cultural station." the expres- 
sion is, perhaps unconsciously, misleading, because there is no dis- 
guising the fact that it is intended to apply alone to mussels. 

In the interest of the popularity of the measure it has been so 
amended as to apparently eliminate the restriction that the proposed 
plant shall be established in the Second Congressional district of Iowa, 
by substituting the words "In the Upper Mississippi River Valley." 
It may be, however, that there is no one so disingenuous as to suppose 
that the passage of the bill would mean anything else than that the 
station will be located in the Second district of Iowa, which is the only 
locality asking for it. • j • • 

We think the proposed legislation is unnecessary, unwise, and vicious 
in principle, and therefore oppose it.
